Question

Which description is a correct way to solve the equation below? x/5 + 4.3 = 12.4

Answer 1

Solution:

Step-1: Subtract 4.3 both sides.

• x/5 + 4.3 = 12.4
• => x/5 + 4.3 - 4.3 = 12.4 - 4.3
• => x/5 = 8.1

Step-2: Use cross multiplication to find x.

• x/5 = 8.1
• => x = 8.1 x 5
• => x = 40.5

Hence, the value of x is 40.5.
